SYSTEM OF ELECTRIC METERING.

Specification of Le'tteral'atent.

Application and July as, 1912. Serial m. 711.005.-

shows a maximum demand for energy during the evening hours, when consumers are using large amounts of energy for lighting purposes. During the other hours of the day the demand for energy is relatively very small. Obviously, it is most desirable that the load curve of the central station be as uniform as possible.

The object of my invention is generally to provide a system of metering electrical energy which willinduce consumers to use energy freely for some purposes, but will tend to restrict the use of-electricity' for one particular purpose. I

More specifically, the object of my invention is to provide a system of metering electrical energy which will induce consumers.

to use such energy freely for power and heating purposes during the period of the central stations light load, but to discourage the consumption of energy for such pureriodof peak load, and thereby improve t e present load curve of the central station. 1

I accomplish the object of my invention by providing asingle meter with a plural- My ofregi-ster dials, which are adapted to record the ener. supplied to a plurality of sets of electric translating devices. One of the register dials is designed to record the total amount of energy consumed. in all the sets of translating devices only during the times that the consumption of energy in one particular set of translati" devices exceeds a predetermined amount. his predetermined amount.m ay of course bejzero, in which case *whenever' any energy. is taken by this particular set of -translating devices,

the registration {will be .npon this dial. The

corded on the other dials.

The translating devices will ordinarily consist of two sets, although my invention is not limited to this particular numberof sets The energy used for lighting purposes will ordinarily beincluded in ohe setof translating devices, and the energy used for power purposes, as motors, electric heaters and the like, wi ll be included in the second set. ,One dialofthe meter will record the total amount of energy consumed in both sets of translating'devices only during the times that Y the energy consumption in the I set com rising the lights exceeds a prede termme amount.v Theener yconsumed at all other times in both sets 0 devifceswill be,

recorded on the second dial. If, therefore, the consumer is charged ahigher' rate for Patented Nov. 4, 1913.

- energy consumed. at other-times will be rethe energy registered on the first dial than for that registered on the second dial, he will be induced to use as littleenergy as pos sible during the times that his consumption is being registered-on this d'ia'l. The consumption Wlll be registered on'this dial only during the times that energy above a pre determined amount is being consumed for lighting purposes, and hence, generally, during the period ef peak load on the central station. Since the rate charged the con ,sumer for energy registered on the second dial is very attractive, he-is induced to use ener freely forfpower purposes during the perioc of light load upon the central'station,

and since he is also induced to; restrict his consumption of energy for power purposes to a minimum amount during the period of peak load, the load curve of the station is materially improved.

The novel features which I consider to be characteristic of my invention will be definitely indicated in the claims appended hereto; the features of construction, and

mode of operation will be understood by A reference to the following description taken in connection with the accompanying draw-,

ings, which show the preferred embodiment of my' invention-and in which Fig'urel illustrates diagrammatically .a metering system employing the princi les' of my invention; and Fig. 2- is'amodi ca-- tion of the inventiom t-he register dialsand' cooperating.mechams.n being omit-ted.

- Referring to Fig. '1 of the drawings there is shown d agrammatically an ampere hour meter 5, adapted to measure the current sup-' plied by a source of electrical energy 6- to two sets of translating devices 7 and 8. The

-devices 7 may consist of lights, while the devices 8 ma consist of motors, electric heaters and t e like.

' -has its winding included in the lighting cireither of the gear trains of the register dials ,justedfthat the changein the registration unit 7, and its-cooperating armature 10 is connected to. a 'linkmechan1sm11. armature and link. mechanism control the movement of a movable gear member 12, which is always in mesh withthe, worm 13 on the meter shaft, and is adapted-to drive 14L and 15. As shown in the figure, when the armature is in its normal s1tion,.which is maintained by an adjusta le spring 16, the

revolutions of the meter shaft are registered on the dial 14. 1

The operation of mynew system of metering is as follows: When' no current being used forlighting purposes thearmature '10 is held in the position shown in Fig. 1 by the spring16, and the current con sulned" 1n the'translatmg devices 8 is regfisteredIon the dial 14. As soon 'as'current is taken by the devices 7 for lighting purposes, the'ma'gnet 9 becomes energized and attracts itsc'o'operating armature 10*,whereby the link mechanism throws'the movable gear 12 into operative relation with the gear train of dial 15. The current taken for lightingpurposes will thus'be registered on dial 15, as well as 'all currenttakeiibythe devices'8 forpowenpurpo'ses during-[the times that current is being taken .for lightn p rp s he-tension of spring 16 may be so adfrom dial 14 to dial 15 will .take place only ,when a predetermined amount of current is'bein-gtaken for lighting purposes by the translatingdevices7. AlthoughI have selected for thefipurpose of illustration in Fig.- lan empere hour-meter, it is obvious'that' my. invention is not limited to this articular type of meter, but is adapted to e carried out with any -t pe of electric meter.

A switch 17 iscohve'niently placed in the meter casins Wh'enthe switch 17 ,1s open e'nergy be taken by both sets of translating devices. 8, but when the switch is closed energy can be taken. by both Sets of translating devices.

The consumer can operate this switch at. will, and when he desires to use energy in' the translating. devices 7" he closes the:

An electromagnet 9 terminal or the winding of the clectromag- The ave shown a modified form vention is not limited to the energy consumed in both sets of transqlat ing devices ,will be registered on the ial Qorr'espondin to dial 15, of Fig. 1.

'An electro agnet 9, provided with apotcntial winding, is arranged to be connected in'parallel with the circuit of the lightng net is permanently connected to one con.-

ductor ofthe supply source and the other terminal of this winding is adapted to be connected'to the otherconductor ofthe supply sourcc through the switch 17, and the current winding of the meter 5 When the switch] 17 is closed the electromagnet 9- is thus energized and operates, likethe electromagnet 9, shown in Fig. 1., to place the gear 1 train of one of the dials, as 15 in Fig. 1, in

operative relation with the meter shaft' The gear trains and dials have been omitted in Fig. 2 in order to sin'iplifythe drawings, but it will be understood that the armature,

ofelectrgmagnet 9 is opcratively connected to these'elcm'cnts in a manner similar to the operative connectlon of armature 10 to register dials l4and15shown in Fig. 1.

It will thus be. apparent thatl haveprovided a metering system which registers the devices upon one dial only during the times that energy, or energy above a predetertotal energy consumed in all the translating mined amount, is being used in one ofthc translating devices.

other dial. The translating devices which The energy consumed at all other times will bra-registered on anthus coiiti-ol -the dial, upon which registra- 1 tion takes placegw fll in practice. ordinarily consist of electric lights? sumer will normally desire'to use his lighting devices only during the period of peak load on the central station it is obvious that Since the conmy system of metering will operate to improve the'load curve of the station. consumer will be encouraged to use energy at the reduced rate when his lighting devices are out of operation, and he will be likewiseinduced to refrain from any large consumptionof energy for power purposes during the: times that his lights are in op- 3 oration, and he is paying the higher rate.

It is obvious that the translating devices 7 ,'may consist of other electrical apparatus than lights. 'Where it is desired to restrict the consumption of electrical energy in all- -classes of apparatus during the times that energy is being consumed 111 a particularclass of ap aratus, then the devices 7 will consist of t e apparatus of the-latter class. In some cases it'may be desirable to merely restrict the use of electricity in a certain class of apparatus, and the devices ,7 may then be composed of this class of apparatus.

Idesireit to be understood that my inparticular construction orarrangement 0 devices here The shown, since many changes, depart from the spirit ofmy invention, will be obvious to those skilled in the art; which changes are within the scope of the present claims. V I
